Title: Seat pipe construction of hydraulic shock absorber
Inventor: YAMAMOTO TOSHIFUMI
IPC: F16F9/34
Filed: 1982-04-28
Abstract: PURPOSE:To freely adjust the effective inner pressure in the hydraulic shock absorber and consequently capacitate the best setting in response to road conditions by a structure wherein a detachable ring joint is provided within the seat pipe of the hydraulic shock absorber in order to raise the oil pressure by means of the fluid resistance caused by the ring joint. CONSTITUTION:When an inner tube 3 advances into an outer tube 2 in compression stroke, the working oil in the outer chamber S2 of the seat pipe is raised its pressure and flowed from the outer chamber S2 through a valve mechanism 26 into the inner chamber S1 of the seat pipe and then past through the ring joint 18 and flowed through an oil passage hole 13 into an upper chamber S3, resulting in raising the oil level in the chamber S3 and consequently reducing the volume of a gas chamber S4 and increasing the pressure in the chamber S4. The impact applied from outside is hereby absorbed and relaxed by means of the damping force caused by the flow resistance produced for the working oil by passing through the valve 26 and the like. In addition, because the fluid resistance is developed in the working oil passing through the ring joint 18 by being throttled therewith, the oil pressure at the upstream side (at the lower part) of the joint 18 is raised higher than the oil pressure at the downstream side of the joint 18 by the value corresponding to the fluid resistance, resulting in raising the effective inner pressure in the shock absorber 1.

Title: Eddy current type coordinate detecting system
Inventor: HITAI YUTAKA
IPC: G06F3/0354
Filed: 1986-03-29
Abstract: PURPOSE:To input accuratly coordinate data by detecting the eddy current produced with shift of a magnet on a conductor with use of a coil wound round the magnet. CONSTITUTION:A mouse 12 contains two magnets 15a and 15b set orthogonal to each other within a plane parallel to a disk plane 11 formed with a conductor like copper, aluminum, etc. Then coils 16a and 16b are wound round both magnets 15a and 15b respectively. When the mouse 12 has a relatively parallel shift to the plane 11, an eddy current is produced at an area where both magnets 15a and 15b are set opposite to each other in response to the moving speed of the mouse 12. The level of the eddy current is shown by the increase function against the relative moving speed. The coils 16a and 16b of magnet 15a and 15b change the inductance owing to the eddy current. This change of inductance is detected by inductance detectors 17a and 17b and this detected inductance value undergoes the arithmetic processing through an arithmetic part 18 for integration of the relative moving speed. Thus the relative shift distance of the mouse 12 is obtained.

Title: Knocking controller of internal combustion engine
Inventor: HEIKO KEIZO
IPC: F02D45/00
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To retrain knocking in the wide range in the high temperature. SOLUTION: Normal ignition timing feedback processing (S200, S300) is stopped when the engine cooling water temperature THW is not less than a high temperature judging reference value THWh, and the ignition timing is set (S110 to S160) on the basis of a previously learned and fixed ignition correction learning value AGKNK without performing learning of a knock control value ADCS. In high temperature, the ignition correction learning value AGKNK learned up to now in the wide range can be applied to control for the ignition timing without being limited by narrow conditions such as the engine speed or the engine load. Since the ignition correction learning value AGKNK is fixed in the high temperature without learning, an abnormal value is prevented from being set in relation to the ignition correction learning value AGKNK.

Title: Automatic tensioner device
Inventor: UMEDA KIYONAGA
IPC: F15B11/02
Filed: 1982-04-30
Abstract: PURPOSE:To improve operational responsibility by thrusting a free piston of an accumulator with a piston of a starting cylinder at the time of starting the operation to change from static friction to dynamical friction. CONSTITUTION:When a motor 20 is started to locate a valve 30 at a neutral position and a valve 31 is switched so that the pressure of a passage 46 is high and the pressure of a passage 45 is low, a piston 13 of a starting cylinder 12 moves downward to thrust a free piston of an accumulator 10. The pressure in an oil chamber 46 is sent to a cylinder 1. Before the cylinder 1 is extended to a neutral position, pressure oil stays in the accumulator, and the piston 11 causes a metal contact due to a break in an oil film, so that the piston 13 generates large static frictional force at the time of starting to move. In this case, the free piston 11 is pushed up with a little stroke by the thrust action of the piston 13 of the cylinder 12 at the initial stage of operation, so that the free piston 11 starts to move smoothly, and the piston 11 smoothly operates with good responsibility.

Title: Composite finite impulse response digital filter
Inventor: KADOWAKI YUKIO
IPC: H03H17/06
Filed: 1988-03-25
Abstract: PURPOSE:To execute a processing by using a RAM having a small storage capacity and to shorten processing time by shifting sub-filters to the least significant side or the most significant side by a shift number corresponding to a control signal. CONSTITUTION:Sub-filters SF1-SF5 are equipped with barrel shifters BS1-BS5 respectively and are shifted by the shift number based on the data of the shift number outputted from a ROM 20 of a control part 200. Consequently, it is unnecessary to store shift data obtained by shifting data inputted to an input terminal IT and data outputted from the sub-filters SF1-SF4 by 0bit-5bits beforehand. Thus, the storage capacities of RAMs 11a-15a can be reduced. Further, since it is unnecessary to shift them beforehand, the time for the shifting is shortened and the processing time can be shortened.

Title: Propeller elevating apparatus for craft
Inventor: KITAMURA SHINZOU
IPC: B63H20/10
Filed: 1980-05-30
Abstract: PURPOSE: To prevent the damage to a propeller, which can be elevated by means of a hydraulic cylinder, by constituting said hydraulic cylinder so that it allows the propeller to be lifted upward when an obstacle collides therewith and makes the propeller perform its function again thereafter.  
     CONSTITUTION: When an obstacle collides with an outboard motor 5 while a craft is traveling forward, an external force is applied to a hydraulic cylinder 6 so as to expand the same. Consequently, in a hydraulic chamber 6c in the hydraulic cylinder 6, a fluid pressure high enough to push a damping valve 6f open is generated, so that the fluid in the hydraulic chamber 6c flows into a hydraulic chamber 6d through the damping valve 6f, and the hydraulic cylinder 6 is expanded to allow the outboard motor 5 to pivot upward. When the outboard motor 5 no more receives the external force from the obstacle, under the outboard motor 5's own weight and a thrust, the piston 6e of the hydraulic cylinder 6 moves downward while pushing out the fluid in the hydraulic chamber 6d into the hydraulic chamber 6c through a check valve 6g. Then, the hydraulic cylinder 6 is contracted so that the outboard motor 5 is allowed to pivot downward, restored to the original position and maintained there.
